Abstract

Un système et un procédé pour surveiller létat dun système de chaînes de batterie sont décrits. Le système comprend un capteur de courant pour chacune des chaînes de batterie et un régulateur configuré pour comparer le courant mesuré avec des critères pour déterminer si la batterie est dans un état demballement thermique. Avant dentrer dans létat demballement thermique, les caractéristiques actuelles de la batterie peuvent indiquer dautres états moins sérieux. Des messages davertissement sont fournis pour des événements sélectionnés et la chaîne de batterie est déconnectée du reste du système lorsquun emballement thermique est détecté. Le système peut fournir une indication locale de létat et peut également servir dinterface avec un réseau de communication pour assurer une surveillance à distance.
